| الوصف: | We put forward and demonstrate experimentally a quantum-inspired protocol that allows us to quantify the degree of similarity between two spatial shapes embedded in two optical beams without the need to measure the amplitude and phase across each beam. Instead the sought-after information can be retrieved by measuring the degree of polarization of the combined optical beam, a measurement that is much easier to implement experimentally. The protocol makes use of non-separable optical beams, whose main trait is that different degrees of freedom (polarization and spatial shape here) cannot be described independently. One important characteristic of the method described is that it allows us to compare two unknown spatial shapes. ; Funding: Ministerio de Ciencia, Innovación y Universidades (CEX2019-000910-S, PID2020-112670GB-I00, PRE2018-085072); Generalitat de Catalunya; FUNDACIÓ Privada MIR-PUIG; Fundación Cellex; European Union’s Horizon 2020 Research and Innovation Programme; European Metrology Programme for Innovation and Research (20FUN02); Agencia Estatal de Investigación. ; Peer Reviewed ; Postprint (published version) |
